ProfessorAnimals get nitrogen from the proteins found in their food. When animals consume plants, they break down the proteins into amino acids, which are then used to build new proteins in their bodies. Nitrogen is an essential component of amino acids, which are the building blocks of proteins in animals.

How do plants get nitrogen compared to how animals get nitrogen?
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
How does nitrogen from the air get into the bodies of plants and animals?
When the animals breathe in nitrogen it goes into their bodies so when they die and decompose the nitrogen they breathed in is now in the soil and also when they fertilize on the land.
Can humans get the nitrogen they need to exist in the air?
No, humans cannot extract the nitrogen they need for survival directly from the air. Instead, we obtain nitrogen through consuming protein-rich foods, such as meat, fish, poultry, dairy products, legumes, and nuts. Our bodies break down these proteins into amino acids, including nitrogen, which are then used for various bodily functions.
True or false animals get nitrogen by eating decomposers?
False. Animals do not get nitrogen directly by eating decomposers. Rather, animals obtain nitrogen by consuming plants or other animals that have already processed and absorbed nitrogen from the environment. Decomposers break down organic matter and release nitrogen back into the soil, where plants can then absorb it.
How do plants and animals get nitrogen if not from the atmosphere?
Plants get nitrogen from the soil through their roots, either in the form of nitrates or ammonium. Animals obtain nitrogen by consuming plants or other animals that have already incorporated nitrogen into their tissues. In this way, nitrogen is cycled between plants and animals in ecosystems.
